mouse sensitivity issue

[McDermotts]

Not sure this is the right newsgroup to post this question, but hoping for a
solution.

For awhile (was occasional and now almost constant), the left click button
on the mouse is ultra sensitive. It's almost, but not quite like an
automatic double click. I've gone over all the adjustable settings, and back
to the defaults, and no change. Sometimes if computer is restarted, the
problem is gone for awhile, but always comes back.

Mouse is a Logitech marble trackball.

Since it works fine some of the time, I think the trackball itself is
probably not the source of the problem.

Thanks for any help, Todd McD

I would think otherwise.
